Agreed on guaranteed tail call optimisation, but it seems[0] that it is at least possible to get it in some cases on some compilers. It seems that calling dtors after the return (somewhat obviously) makes it impossible to do it, although appropriate scoping might help. I however didn’t play around with it, merely rephrasing what [0] wrote. I’m not sure about threads (and how light/heavy those currently in C++11 are).
